Equilibrium constants aren't changed if you change the concentrations of things present in the equilibrium. The only thing that changes an equilibrium constant is a change of temperature.
The position of equilibrium is changed if you change the concentration of something present in the mixture. According to Le Chatelier's Principle, the position of equilibrium moves in such a way as to tend to undo the change that you have made.
The dissociation constant describes the extent to which a compound breaks apart into its ions in a solution, specifically for weak acids or bases. The equilibrium constant, on the other hand, describes the ratio of product concentrations to reactant concentrations at equilibrium for a chemical reaction.

Why can the concentration of water be ignored in the equilibrium expression for water?
The concentration of water remains relatively constant compared to other reactants/products in solution, so it does not significantly affect the equilibrium constant. Additionally, water is a solvent that is usually present in large excess, so changes in its concentration have minimal impact on the equilibrium position.
How was the equilibrium constant of a reaction determined?
The equilibrium constant of a reaction is typically determined experimentally by measuring the concentrations of reactants and products at equilibrium, and then applying the law of mass action to calculate the constant. Alternatively, the equilibrium constant can also be calculated from thermodynamic data using the relationship between free energy change and equilibrium constant.
What is the value of the equilibrium constant at 25 and degC for the reaction between Cr(s) and Cu2 plus (aq)?
The equilibrium constant for the reaction between Cr(s) and Cu2+ (aq) cannot be determined without knowing the specific reaction equation. The equilibrium constant (K) is a unique value for each specific reaction at a given temperature.
What is the difference between Kc and Kw for water?
Kc is the equilibrium constant for a chemical reaction involving water, whereas Kw is the equilibrium constant for the autoionization of water to form hydronium and hydroxide ions. Kw has a fixed value at a given temperature (1.0 x 10^-14 at 25°C), while Kc can vary depending on the specific chemical reaction.
What products are formed when the aqueous ammonia is added to polyacrylic acid and and how to calculate the pH of the produced solution?
When aqueous ammonia is added to polyacrylic acid, the products are the ammonium salt of polyacrylic acid and water. To calculate the pH of the solution, you would need to consider the equilibrium between the acid (polyacrylic acid) and its conjugate base (ammonium polyacrylate). You can determine the pH based on the concentration of the acid, the equilibrium constant, and the dissociation of the acid.
What is the difference between q and K in determining an equilibrium constant?
K is the equilibrium constant, Q is a concentration.
What is the Difference between static equilibrium's and dynamic equilibrium?
Static equilibrium refers to a system at rest where all forces are balanced, while dynamic equilibrium refers to a system in motion where the rate of change is constant. In static equilibrium, objects are stationary, while in dynamic equilibrium, objects are moving at a constant speed and direction.

Difference between rate constant and specific rate constant?
There is no difference between them they are same rate constant is another name of specific rate constant

What is the difference between a constant in a graph and a constant in a experiment?
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
What is Kd?
Kd, also known as the dissociation constant, is a measure of the affinity of a ligand for its binding site on a protein. It quantifies the equilibrium between a protein-ligand complex and the unbound forms. A lower Kd value indicates higher affinity between the protein and ligand.
What is the relationship between speciation and the theory of punctuated equilibrium?
No difference.
What is the difference between ordinary prism and constant deviation prism?
difference between ordinary prism and constant deviation prism
Difference between attenuation constant and phase constant?
nothing
What is the difference between equilibrium and disequilibrium price?
Equilibrium is when supply and demand is balanced or equivalent, whereas disequilibrium doesn't attain equilibrium which is either above or below equilibrium.
